Put another pullback motor in but backwards and you’ve got yourself infinite energy

You've just revolutionized green energy! I expect your Nobel Prize is in the mail!

Better start working on a speech!

Nobel committee? Yes... that one right there... they've just solved the world's energy problems forever, please give them all the medals!

Sorry we don't give medals anymore. Last time we gave out a medal to someone, Trump invaded their country and only left when the medal was given to him. Our insurance company just won't allow it anymore.

You invented recuperation braking. Nice.
